(May 17, 2008) The 7.8 earthquake that shook Sichuan Province in the afternoon of May 12, killing an estimated 50,000, is posing a continuing threat as the untold damage to hydropower stations and reservoir dams upstream on the Min River (the Minjiang) becomes apparent, reports Chinastakes.
(May 16, 2008) China’s Ministry of Water Resources on Friday dispatched nine emergency repair teams to Sichuan to assess the conditions of reservoirs after Monday’s massive earthquake, reports Xinhua.
(May 15, 2008) Though the deadly Wenchuan earthquake was the result of tectonic stresses, experts are concerned that the filling of the Three Gorges dam’s enormous reservoir may have induced or exacerbated the earthquake.
(May 15, 2008) As China reels following Monday’s earthquake, scientists are just beginning to figure out the complex mechanics that triggered a temblor of such destructive force and widespread reach.
(May 14, 2008) In the wake of China’s massive earthquake, and amidst the desperate recovery effort, Chinese authorities have still more to worry about as damage to existing dams becomes evident.
(May 14, 2008) The world’s earthquake experts have identified tectonic plate movements as the cause of this week’s earthquake in southwestern China. But the question now is did the filling of the massive Three Gorges reservoir, which reaches the southeastern part of the Sichuan Basin, trigger seismic activity in what has always been an earthquake-prone region?
(May 13, 2008) The Zipingpu dam has been left with dangerous cracks as a result of Monday’s deadly earthquake, AP reports.
(May 13, 2008) Earthquake forecasting remains a “hard nut” to crack, a Chinese expert told reporters here on Tuesday.
(May 13, 2008) The earthquake in the Sichuan Province of China on Monday was a result of a continuing collision between India and Asia.
(May 1, 2008) There are different types of dams classified by the material and design used in construction. These differences influence how and why dams fail. A dam can be classified by its material, indicating whether it is earthen or concrete. Dam components can also include iron, steel or timber or a combination of any of the above.
(May 1, 2008) The Richter scale provides an objective way of measuring and comparing the size of earthquakes using a mathematical device.
(April 8, 2008) Fan Xiao, a geologist at the Bureau of Geological Exploration and Exploitation of Mineral Resources in Sichuan province, is quoted saying recent landslides in the Three Gorges area are directly linked to filling the reservoir. Water first seeps into the loose soil at the base of the area’s rocky cliffs, destabilizing the land and making it prone to slides.
(February 20, 2008) Chief engineer of the Three Gorges Reservoir Area Disaster Control Headquarters says the number of landslides and collapses in the dam’s reservoir area have nearly doubled between 2001 and 2003, reports Caijing magazine.
The possible earthquake issue due to Three Gorges reservoir has been emphasized by the government for a long time, and extensive researches have been made on the issue involved in the rock, geologic structure, osmosis, etc. A 300~800 m deep-hole earth stress observation is carried out at dam and reservoir site and the earthquake intensive observation is made on some fracture zones around the dam. According to the researches, the geologic structure is stable, and has no geological background for a
Geographical overview of the Three Gorges dam and reservoir, China—geologic hazards and environmental impacts
(2008) The Three Gorges dam and reservoir are an ongoing project that will involve a continuous process of construction, maintenance, monitoring, evaluation, and modification. Some of the history, construction characteristics, hydropower statistics, environmental and population impacts, monitoring, and current and potential hazards of the massive dam project are presented in this Microsoft PowerPoint® format.
